Shark

Ax was changing, too. It almost broke my concentration, watching him. In their normal forms Andalites are strange enough. When they morph it is totally bizarre. Instead of two legs shriveling and disappearing, it was four. And then there were the stalk eyes. And the tail, which lost its scythe blade but split into a new kind of tail, with a long, raked, vertical blade and a shorter lower blade.

The water swept up to my neck, but by that point I was more dolphin than human.

BA-BOOOOM!

The explosion shuddered through the dome. It rattled my teeth. I felt like my eardrums would explode.

<Yeerks,> Ax said. He said the word in our heads the way his brother had. With hatred and rage so deep it was impossible to comprehend it.

BA-BOOOOM!

A second explosion! Suddenly the exterior door opened and we swam out in a rush. Four dolphins and one . . .

Shark!

I'd been distracted by the explosions.

Ax had morphed a shark.
